f) Continuity test
Make sure that all circuit parts, circuits and com-
ponents and other objects of measurement are
disconnected from the voltage and discharged.
- Switch on the DMM and select the measuring range
.
Press the button
to switch measurement functions.
The symbol for continuity test now appears in the display.
Pressing this button again takes you to the next measuring
function, etc.
- Plug the red measuring line into the
Ω
measuring jack (7)
and the black measuring line into the COM measuring
jack (8).
- A value of less than 50 Ohm is measured as continuity and a
beep sounds. The measuring range is up to 1000 Ohm.
- If “OL” (overload) appears on the display, you have exceed-
ed the measuring range or the measuring circuit is inter-
rupted.
- Always remove the measuring lines from the object to be
measured after completion of the measurement and switch
off the DMM.
g) Capacity measuring
Make sure that all circuit parts, circuits and
components and other objects of measurement
are disconnected from the voltage and dischar-
ged.
Always observe polarity with electrolyte
capacitors.
- Switch on the DMM and select the measuring range
with the rotary control (4). Press the button
to switch
measurement functions. The display shows the unit “µF”.
Pressing this button again takes you to the first measuring
function, etc.
- Plug the red measuring line into the V measuring jack (7)
and the black measuring line into the COM measuring
jack (8).
Due to the sensitive measuring input, the display may
show a value if the measuring lines are “open”. By select-
ing the function
, the display is set to “0”.
The basic value (rel difference) is displayed in the upper,
small display. The autorange feature is deactivated.
- Now connect the two measuring prods (red = plus/black = minus) with the object to be measured (capacitator).
After a short time the display shows the capacity. Wait until the displayed value has stabilised. This may take a few
seconds for capacities of >40 µF.
- If “OL” (overload) appears on the display, you have exceeded the measuring range.
- Remove the measuring lines from the object to be measured after completion of the measurement and switch off
the DMM.
